ptu vs methimazole in pregnancy

Groups exposed to PTU had a lower risk of major neonatal congenital malformations compared to groups exposed to MMI/CMZ. Rongjing Song and Hepu Lin independently performed the process of study selection and data collection. The results indicated that exposure to MMI/CMZ significantly increased the risk of neonatal congenital malformations compared to PTU exposure. Antithyroid drugs (ATDs) are the mainstay treatment for hyperthyroidism and include propylthiouracil (PTU), methimazole (MMI) and its prodrug carbimazole (CBM) 1.However, concerns have been raised about hepatotoxicity by ATDs 2, 3 due to numerous reported PTU-induced 4-6 and MMI/CBM-induced hepatotoxic cases 7, 8.Additionally, PTU was reported to cause 23 liver transplants from . Graves’ disease is the most common cause of gestational hyperthyroidism. Pregnancy. New data have also emerged from animal studies. Both block thyroid hormone synthesis by preventing iodination of tyrosine residues in thyroglobulin; additionally, propylthiouracil acts peripherally to inhibit the conversion of . The impact of this issue on obstetrical practice was also shown in a retrospective commercial insurance claims analysis performed in the United States using a database containing 904 497 women (5). Li et al. Abalovich M, Amino N, Barbour LA, et al. Search terms included hyperthyroidism, Graves' disease, pregnancy, propylthiouracil, and methimazole. the Newcastle-Ottawa Scale; OR, The ascertainment of exposure was unclear in Clementi’s study [6]. Methimazole is not used in the first trimester of a pregnant woman because it causes congenital . Found inside – Page 390... in patients who are considered in remission of Graves disease or an unavoidable shift from methimazole to PTU has to take place very early in pregnancy. PTU exposure, however, was associated with developmental defects that include lateralization defects, situs inversus, and malrotation of the intestinal system. Propylthiouracil can be given but the blocking-replacement regimen is not suitable. PTU blocks conversion of T4 to T3 in the periphery, methimazole does not (faster) Therefore, we concluded that the risk of major neonatal congenital malformations following exposure to MMI/CMZ only during pregnancy was significantly higher than that following exposure to PTU. These observations provide a biological explanation for clinical studies that describe situs inversus, other lateralization, and gut miscoiling defects associated with prenatal PTU exposure (11, 12). Clipboard, Search History, and several other advanced features are temporarily unavailable. Effects of propylthiouracil and methimazole on fetal thyroid status in mothers with Graves' hyperthyroidism. This full-color volume offers valuable information on thyroid cancer and non-cancerous lesions, the effect of drugs on thyroid function, genetic disorders, and more in an accessible, easy-to-read consistent format. A group that changed from one drug to another was defined as an “MMI/CMZ & PTU” group in our study. Monitoring:-Routine monitoring of TSH and free T4 levels is necessary to avoid under or over treatment If you are planning pregnancy, become pregnant, or think you may be pregnant, contact your doctor. Study designs included case–control studies, prospective cohort studies, and retrospective cohort studies. FDA Adverse Event Reporting System files for PTU and MMI were reviewed. 2013 Feb;27(2):684-91. doi: 10.1096/fj.12-218073. Eight items were included in the three perspectives (four items in selection, one item in comparability, and three items in outcome/exposure). This book offers the collaborative expertise of dozens of critical care physicians from different specialities, including but not limited to: emergency medicine, surgery, medicine and anaesthesia. Birth defects or perinatal problems associated with PTU included anal stenosis, aplasia cutis, congenital heart disease, Dandy Walker syndrome, skeletal dysplasia, gastrointestinal abnormalities, limb defects, polydactyly, and skull defects.

Carbimazole and MMI are associated with less severe hepatic injury and should be preferred when choosing thionamides as a treatment option. FDA notified healthcare professionals of the risk of serious liver injury, including liver failure and death, with the use of propylthiouracil (PTU) in adult and pediatric patients. To eliminate the influence of exposure before pregnancy, we excluded the two studies conducted by Andersen and Korelitz. Statistical analysis was performed using Review Manager software (version 5.3). Competing interests: The authors have declared that no competing interests exist. Regarding this later point, hypothyroidism during pregnancy is associated with an increased risk of spontaneous abortion and potential possible reduced intellectual capacity of the offspring (16). https://doi.org/10.1371/journal.pone.0180108.t007, https://doi.org/10.1371/journal.pone.0180108.t008, https://doi.org/10.1371/journal.pone.0180108.t009, https://doi.org/10.1371/journal.pone.0180108.t010.

Found inside – Page 201In terms of maternal serum drug concentrations, there are no substantial alterations in the pharmacokinetics of PTU or methimazole during pregnancy. The characteristics of the 12 included studies are shown in Table 1. Methimazole and Propylthiouracil (PTU). The definitions of “No ATD group” and “Control group” were slightly different in each included study (see Tables 2 and 3). In the rest of the adult population, it should be used with caution. When ciliary function of the gastrocoel roof plate, which is similar to the nodal region of mammals that governs left-right developmental lateralization, was examined, PTU was found to disrupt the normal pattern of left-to-right ciliary flow (15). The study is based on propylthiouracil and methimazole (the active ingredients of Propylthiouracil and Methimazole, respectively). No, Is the Subject Area "Pregnancy" applicable to this article?

Benavides VC, Mallela MK, Booth CJ, Wendler CC, Rivkees SA. Seven studies provided a comparison between PTU exposure and “No ATD” exposure and no differences were observed between the two groups (OR 1.10; 95%CI 0.92 to 1.32; P = 0.30). So, how risky is PTU? Main results from the observational studies [13,14,15,16] that detected an association between the use of antihyroid drugs in early pregnancy and birth defects.The figure illustrates the prevalence of birth defects in non-exposed children and in children exposed to maternal treatment with Propylthiouracil (PTU) or Methimazole (MMI) in early pregnancy. Recognizing that basic teratogenicity testing had not been performed in standard animal models, a series of National Institutes of Health-funded studies were conducted in different animal models (14, 15). In mice treated with PTU during embryogenesis, delayed neural tube closure and cardiac abnormalities were observed (14). I'd say, first of all, congratulations for being an informed patient. The safest option is often to use propylthiouracil in early pregnancy, changing to carbimazole in the latter months. This result agreed with the report in the Food and Drug Administration Adverse Event Reporting System files, in which there were 19 reports of birth defects following exposure to PTU (5% of all reports) and 40 reports following exposure to MMI (6.4% of all reports). Dosing for thyroid storm in adults is as follows: PTU 200 mg every 4 hours or methimazole 20 mg orally every 4-6 hours; these drugs may need to be administered through a nasogastric tube. Drugs. Two studies involved exposure before pregnancy [18, 19] and another 10 studies involved exposure only during pregnancy. Hyperthyroidism in pregnancy is associated with a increased incidence of low birth weight, preterm birth and admission to the neonatal intensive care unit. These meds should be taken after breastfeeding. Also called Thionamides.

Among 52 types of malformations analyzed, situs inversus, kidney dysgenesis, and cardiac outflow tract defects were found to be associated with prenatal exposure to PTU (12). No differences were observed between the group exposed to PTU and the “No ATD” or “Control” groups. In order to assess the effect of propylthiouracil (PTU) or methimazole (MMI) pretreatment on patient outcome after radioiodine therapy, we examined 100 patients with Graves' disease 3, 6, 9, and . While, some physicians may prefer to use methimazole throughout pregnancy, Hershman said he believes that PTU is a . Groups exposed to MMI/CMZ had a significantly increased risk of major neonatal congenital malformations compared to “No ATD” groups. Fig 3 illustrates the results after removing two studies that involved exposure before pregnancy. Propylthiouracil (PTU) and Methimazole. Our GMP-Approved propylthiouracil is a white to off-white crystalline powder 99% pure. The selection of PTU versus methimazole for the treatment of Graves' disease during pregnancy should not be based solely on the following assumptions: that PTU crosses the placenta less than methimazole, that PTU leads to less fetal hypothyroidism, or that exposure to methimazole during pregnancy leads to decreased intellectual function in children. Grading of Recommendations Assessment, Development, and Evaluations; NOS, antithyroid drugs; GRADE, Identified articles were then reviewed for additional sources. [5]. Fumarola A, Calvanese A, Di Fiore A, Dainelli M, D'Armiento M. Zhang LH, Li JY, Tian Q, Liu S, Zhang H, Liu S, Liang JG, Lu XP, Jiang NY. Propylthiouracil has been considered as the first-line drug for treatment of hyperthyroidism in the first trimester of pregnancy. Fourth, the exact time of exposure during pregnancy was not described in each individual trial; therefore, we cannot provide evidence for a safer administration time of ATDs during pregnancy. Propylthiouracil versus methimazole in treatment of Graves' disease during pregnancy. No, Is the Subject Area "Neonates" applicable to this article? Therefore, in the absence of a compelling indication for the use of methimazole, PTU should still be considered as the first-line agent in the treatment of Graves' disease during pregnancy. Iodides. Methimazole (Tapazole) ราคาถูก half-lifeนาน ผลข้างเคียงต่ำ . 2014. Tables 2 and 3 show the baseline data extracted from each study. Graves' Disease Methimazole Propylthiouracil Antithyroid Drugs Long-Term Therapy Continuous Therapy 1. 2014) and they are the treatment of choice for thyrotoxicosis in pregnancy (Diav . Therefore, antithyroid agents, including methimazole (MMI)/carbimazole (CMZ) (pro-drug of methimazole) and propylthiouracil (PTU), have become the standard treatment for hyperthyroidism during pregnancy. . PTU specifically may cause life-threatening hepatotoxicity, while methimazole specifically acts as a teratogen during pregnancy. The three main types of antithyroid medication are Methimazole, PTU, and Carbimazole. Treatment options for hyperthyroidism include surgical treatment (partial or complete thyroidectomy), radioactive iodine, and antithyroid drugs (ATDs) [3]. For pregnant women with hyperthyroidism, exposure to MMI/CMZ significantly increased the incidence of neonatal congenital malformations compared to exposure to PTU and no antithyroid drug exposure; however, no differences were observed between PTU exposure and no antithyroid drug exposure. Introduction. However, their use is controversial owing to their adverse effects. Conclusions: Therefore, the second part of our meta-analysis evaluated the 10 included studies in which the exposure was only during pregnancy. Heterogeneity was measured using I2 statistics (I2 < 50% was regarded as homogeneity) and a fixed-effects model was used in this study. Found inside – Page 1081... increased , or decreased during pregnancy , although they remain within the ... such as propylthiouracil ( PTU ) , methimazole , and propranolol . Graves' hyperthyroidism: how long should antithyroid drug therapy be continued to achieve remission? Exposure to MMI/CMZ only during pregnancy significantly increased the risk of neonatal congenital malformations compared to that associated with exposure to PTU (OR 1.90; 95%CI 1.30 to 2.78; P = 0.001). Objective: Funnel plots are shown in the S1 and S2 Figs and indicated that the three studies that involved a small sample size (sample size in exposure groups was less than or equal to 30) were the major source of heterogeneity across the studies [16, 20, 21]. It is well recognized that medical management of GD during pregnancy is challenging and can be associated with abnormal swings in thyroid hormone levels. Interestingly, these studies also revealed that the rate of early-terminated pregnancies was much greater among women prescribed MMI (31%) than PTU (9%) (5). Methimazole (MMI) and propylthiouracil (PTU) are the standard anti-thyroid drugs used in the treatment of hyperthyroidism in pregnancy. One infant was . Asher Ornoy. The risk of major neonatal malformations was significantly less in those exposed to PTU compared to that in those exposed to MMI/CMZ (OR 1.73; 95%CI 1.15 to 2.59; P = 0.008). Our meta-analysis follows the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guideline. Therefore, there is a strong need to control hyperthyroidism during pregnancy. The results indicated that groups exposed to MMI/CMZ had a significantly increased risk of neonatal congenital malformations compared to “No ATD” groups (OR 1.88; 95%CI 1.33 to 2.65; P = 0.0004). Combination therapy was associated with urinary system malformations (10). However, a maximum of two stars can be given for an item in the comparability category. Data Availability: All relevant data are within the paper and its Supporting Information files. The management of the pregnant woman with a medical problem presents the clinician with particular problems. Radioactive iodine therapy is contraindicated during pregnancy (17). The results indicated that most of the data in this meta-analysis were from studies with a relatively high quality. This book focuses on such issues encountered during pregnancy including physiology and pathophysiology of pregnancy, hypertension, preeclampsia, various electrolyte disorders, nephrolithiasis, pharmacological management in the pregnant ... These drugs are also used to hyperthyroidism in pregnant women, as well, except for the fact that they used considering the trimester of the woman. use PTU in the first trimester. MMI, Somnuke PH, Pusuwan P, Likitmaskul S, Santiprabhob J, Sawathiparnich P. J Med Assoc Thai. The duration of exposure was different for each individual study. The teratogenic effect of MMI may be associated with placental transfer [23, 24]. According to literature, propylthiouracil is preferred over methimazole at your gestational age since methimazole has been associated with birth defects at this stage. Is the Subject Area "Congenital anomalies" applicable to this article? In adults, thionamide treatment is usually started with high doses (20 to 40 mg/day of methimazole or 200 to 400 mg/day of propylthiouracil). Unable to load your collection due to an error, Unable to load your delegates due to an error. Propylthiouracil (PTU) is a medication used to treat hyperthyroidism. The authors identified 1426 women treated with MMI, 1578 women treated with PTU, and 2065 women who received no medication for the treatment of GD during the first trimester of pregnancy (11). Found inside – Page 142High fetal TSH rates were 21% in the PTU group and 14% in the methimazole group. ... or that exposure to methimazole during pregnancy leads to a decreased ... After duplicates were removed, 850 records remained; however, 820 records were further removed after reading the titles and abstracts. Tapazole (methimazole) can be an effective oral treatment . “No-Response Rate” was not mentioned in any case–control study included in this study [6, 7, 13]. Fig 1 shows the process of study selection. Studies published in English or Chinese and only studies with full text available were included in this meta-analysis. Citation: Song R, Lin H, Chen Y, Zhang X, Feng W (2017) Effects of methimazole and propylthiouracil exposure during pregnancy on the risk of neonatal congenital malformations: A meta-analysis. Three studies involved a change in drug exposure from MMI/CMZ to PTU (or vice versa) during pregnancy [18–20]. versus; /, We found that the ascertainment of exposure and the assessment of outcome were unclear in the Gianantonio study [15]. Studies of frog embryos, which facilitate treatment of embryos at earlier developmental stages than possible in mice, were also performed (15). Propylthiouracil During Pregnancy and Breastfeeding. The panel also called for additional basic research and epidemiological and clinical studies (9). https://doi.org/10.1371/journal.pone.0180108.t001, https://doi.org/10.1371/journal.pone.0180108.t002, https://doi.org/10.1371/journal.pone.0180108.t003. Bahn Chair RS, Burch HB, Cooper DS, et al. In addition, there were no differences in Table 4 illustrates the total star template for each individual study. Considering the current warnings that MMI may be associated with an increased risk of birth defects, it is possible that women who had been taking MMI were encouraged to or felt the need to terminate their pregnancies. methimazole crosses the placenta and enters breast milk (may be teratogenic) Thyroid hormones. These results suggested that uncontrolled hyperthyroidism before pregnancy maybe associated with the occurrence of neonatal congenital malformations, and therefore, control of hyperthyroidism before pregnancy is recommended. PTU is the drug of choice during pregnancy because Tapazole® more readily crosses the placenta and has been associated with scalp lesions in the fetus. Early case reports described aplasia cutis associated with the use of methimazole (MMI) during pregnancy (2), whereas there was a paucity of reports of birth defects in infants born to mothers taking propylthiouracil (PTU). van Veenendaal NR, Ulmer B, Boskovski MT, Fang X, Khokha MK, Wendler CC, Blum M, Rivkees SA. The publication year ranged from 1984 to 2016. . The results indicated that exposure to MMI/CMZ significantly increased the risk of neonatal congenital malformations compared to exposure to PTU (OR 1.38; 95%CI 1.08 to 1.77; P = 0.01). Abstract. There are approximately 600,000 60,000 new cases of Graves' diagnosed in the US each year. As expected, the risk of neonatal congenital malformation in the “MMI/CMZ & PTU” groups was significantly higher than that in the “No ATD” or “Control” groups, which further suggested that MMI/CMZ was associated with a higher risk of birth defects. The results of the comparison between MMI/CMZ and PTU agreed with previous results and indicated that PTU was safer than MMI/CMZ with respect to the risk of neonatal congenital malformations after we limited the exposure to only during pregnancy. Methimazole is used to treat hyperthyroidism, especially when it is caused by Graves' disease. Propylthiouracil is an antithyroid medication used in the therapy of hyperthyroidism and Graves disease. Lactation and Breast-feeding Thionamides are absorbed and excreted into the breast milk, thus putting the infant at risk of developing hypothyroidism. OBJECTIVE: Our purpose was to demonstrate that propylthiouracil and methimazole are equally effective and safe in the treatment of hyperthyroidism during pregnancy.STUDY DESIGN: Between 1974 and 1990 records were available on 185 pregnant patients with a history or diagnosis of hyperthyroidism. Therefore, PTU was recommended during pregnancy with respect to neonatal congenital malformations. An essential pocket manual for anyone who treats children "This is a unique and novel approach to a pediatric handbook. Recognizing that these studies involved short-term treatment with ATDs during pregnancy, additional formal toxicology studies are now being performed using mice and rats treated with PTU or MMI for the entire duration of pregnancy and evaluated at the end of gestation, after birth, and in adulthood. Antithyroid drugs, such as methimazole (MMI) and propylthiouracil (PTU) have been used to treat hyperthyroidism during pregnancy. Prevalence of thyrotoxicosis, antithyroid medication use, and complications among pregnant women in the United States. Found inside – Page 526Drug Interactions References Summary Methimazole crosses the human ... to methimazole (6.8%, P=0.6) or PTU (6.4%, P=0.4) vs. nonexposed children (8%). The exposure groups included “MMI/CMZ,” “PTU,” or “MMI/CMZ and PTU.” Three studies involved a sample size in the exposure group that was less than or equal to 30 [16, 20, 21]. found that gestational hyperthyroidism was associated with an increased risk of labor induction, preeclampsia, superimposed preeclampsia, threatened and observed preterm births, and neonatal intensive care unit admission [2]. Found insideCritical care in obstetrics is an upcoming specialty in the developing countries. This book is first of its kind as there are very few books written on this subject. Pregnant: PTU is a pregnancy category D drug. Found inside – Page 274Antithyroid medication should not be discontinued either pre-pregnancy or ... like propylthiouracil (PTU), methimazole (MMI) are used during pregnancy. However, no differences were found between the “MMI/CMZ” and “Control” groups (OR 2.75; 95%CI 0.58 to 12.96; P = 0.20). Therefore, antithyroid agents, including methimazole (MMI)/carbimazole (CMZ) (pro-drug of methimazole) and propylthiouracil (PTU), have become the standard treatment for hyperthyroidism during pregnancy. Because of these combo of factors, it's recommended to use PTU only in the first trimester to decrease the risk of aplasia cutis in the fetus, and then switch to methimazole after that to avoid the hepatotoxicity of PTU. Pregnancy outcome, thyroid dysfunction and fetal goitre after in utero exposure to propylthiouracil: a controlled cohort study. In addition, other types of thyroid disorders, such as toxic multinodular goiter or solitary autonomously functioning nodules, induce gestational hyperthyroidism. Sensitivity analyses were conducted after excluding three studies with a small sample size in the exposure group (less than or equal to 30), which indicated that these results were robust. Bariatric Surgery: It’s Not Just Incretins! More trials are needed to confirm this conclusion in the future. Epub 2012 Nov 12. Yes Methimazole causes fetal anatomical abnormalities; hence, if it is necessary to use antithyroid drugs in pregnancy, PTU is preferred in the first trimester with the lowest possible drug dose usage. No differences were observed between groups exposed to PTU and “No ATD” or “Control” groups. Twelve studies involving 8028 participants with exposure to different antithyroid drugs during pregnancy were included in this study; however, only 10 studies involving 5059 participants involved exposure to different antithyroid drugs exactly during pregnancy. After the Chernobyl nuclear reactor explosion, for example, many pregnancies in Greece were terminated despite not being at risk (13). No, Is the Subject Area "Birth defects" applicable to this article? No difference was observed between MMI/CMZ and “Control” groups. The risk of associated birth defects may range from 2–10% and may differ among PTU and MMI. Experts address the myriad concerns for women with thyroid disease who are trying to or have conceived.
